Jesse Jackson hospitalized with COVID

Civil rights pioneer Jesse Jackson Sr. and his wife have been hospitalized after testing positive for COVID-19.

The 79-year-old and his wife, 77-year-old Jacqueline Jackson, are both being treated at Northwestern Hospital in Chicago, according to a statement from the Rainbow PUSH Coalition, the nonprofit he founded in 1996. The statement said doctors were "monitoring the condition of both," but provided no further details.

Jackson was inoculated against the virus in January with the Pfizer vaccine. He also spent three weeks in a rehab center in February and March after gallbladder surgery.

The former Washington, D.C., shadow senator has been a prominent civil rights activist for 60 years, first joining forces with Martin Luther King Jr. in the 1960s and working with King's Southern Christian Leadership Conference.

Jackson also ran for president in 1984 and 1988.

The activist was arrested earlier this month as part of a group in Washington, D.C., protesting restrictive voting rights being implemented in many states, including Georgia and Texas. One week earlier, he'd been arrested as part of a large group during a sit-in at Arizona Sen. Kyrsten Sinema's office.
